To prevent duplicate documents from being created in QuickBooks Online, you should start the data import at the time of the last order you've manually entered into QuickBooks.
For instance, if you enter all of Monday's orders into QuickBooks Online on Tuesday, then you'll want to start the syncing at 12:01AM on Tuesday. This way, our service will begin syncing right where you left off, allowing for a seamless integration.
Similarly, you can enter all orders up to 5PM on Monday and set our service to sync all orders after 5PM.
Once you choose the date and time to start syncing, you no longer have to be present or do anything else. We'll take it from there.
You won't be able to change the start date and time once you choose it. This is to prevent duplicate documents.
If you change your mind about the date and time, please contact us so that we can help you.
